. To all whom it may concern.'

Be it known that l, Lome W. OSTMANN, a citizen of the United States, residing at St. Charles, in the county of St. Charles and State of Missouri, have invented certain new pneumatic qualities without the use of inner tubes and valves and which is not subject to puncture.

Another object of the invention is to provide a cushion tire which is comparatively simple, strong, durable and inexpensive in construction, eflicient and reliablein operation, and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter Vfully described and claimed.

lin the accompanying drawings in which similar reference characters designate corresponding parts throughout the several i views,

bands l and 2 and arranged Figure l is a view of a portion of a tire constructed in accordance with this invention, showing it partly in longitudinal section and partly in side elevation, and

Fig. 2 is a transverse sectional view of the tire taken substantially on the plane indicated-by the line 2 2 of Fig. l.

Referring more particularly to the drawings, the numerals l and 2 designate inner and outer spaced circularbands respectively. These bands l and 2 are made of suitable flexible material, preferably canvas.

lThe numerals 3 and 4 represent inner and outer continuous sinuous bands respectively, which are also made of canvas or other suitable iexible material. These sinuous bands 3 and 4 are disposed between the circular in respective parallel relation, that is, they are arranged so that the corresponding wportions of their curves occupy corresponding circumferential pcsitions with respect to the circular bands l and 2. The inner portions of the of resiliency,

inner sinuous band 3 are riveted or otherwise suitably secured to the circular band l, and the .outer portions of the sinuousband 4 are similarly secured to the outer circular band 2, the points cfconnection of the sinuous bands with the circular bands being arranged in staggered relation.

Disposed between the sinuous bands 3 and 4 is an intermediate 5, the latter being continuous sinuous band also made of canvas or i other suitable flexible material, and being arranged with its curves arranged opposite i to the similar curves of the bands 3 and t. The inner portionsof the band 5 are riveted or otherwise suitably secured to the outer g portions of the band B and the outer portions of the band 5 are similarly secured to` band 4. This?V Y ings 6 between the sinuousbands 3, 4 and the inner portions ofv the forms substantially diamond-shaped open- 5, these openings extendin transversely of the tire as clearly shown in Fig. 2 of the drawings. y

The numeral 7 designates' diamond-shaped blocks of rubber or other suitable cushioning tween the inner sinuous band 3 and the intermediate sinuous band 5 to the respective inner and outer portions of the curves of the same, and between the .intermediate sinuous band-5 and outer sinuous band 4 to the respective innerand outer portions'of the curves of these bands. The lbloclrs 7 are smaller in cross section than the area of the openings 6 so as to permit them to be com pressed as the width of decreased, such action taking place when pressure is applied tothe tire.

. he various bands `of the tire are coated with rubber so as to protect them from moisture or the like, and the spaces between the inner circular band 1 and inner sinuous band 3 and the outer circular band 2 and outer sinuous band 4 are filled with rubber. At the same timethe outer circular band 2 is formed with a tread surface 8 which is preferably provided with transverselyV extending ridges 9 to form an anti-slipping surface for the tire, but which -if desired may be left entirely plain.

lt will be seen that a tire constructed as above described will possess a great amount but will not easily get out Aof order as there are no puncturable pneumatic inner tubes, and neither are there inflat-v ing valves.

material secured at opposite corners bethe openings are in the minor details of construction may be resorted to Without departing from the p y outer continuous sinuous spirit of the invention as claims.

What is claimed is: 1 I 1. A cushion tire including spaced inner and outer circular flexible bands, inner and flexible bands disposed between said circular bands and sedefined in the cured in staggered relation at their inner and outer portions respectively to said inner and outer circular bands respectively` anV intermediate continuous sinous flexible band disposed between said sinuous bands and secured at its inner and outer portions to the outer and inner portions respectively of-vsaid inner and outer sinuous bands respectively, and cushion blocks disposed between said inner and intermediate sinuous bands and said intermediate and outer sinuous bands.

. 2. A cushion tireincluding spaced inner and outer circular flexible bands, inner vand outer continuous sinuous flexible bands disposed between said circular bands and arranged in respective parallel relation, the

vposed between said sinuous ranged with inner and-louter portions of said inner and outer sinuous bands respectivelyA being .secured in staggered relation to 'said inner and outer circular bands respectively7 an inter-Y mediate continuous sinuous flexible band disbands and arvits curves arranged lopposite to the curves ofthe4 latter, thev inner and outer portions of said intermediate band being secured to the outer and innenportions my hand.

respectively of said inner and outer sinuous bands respectively, and cushion blocks disposed between said inner and intermediate sinuous bands and said intermediate and outer sinuous bands.

A cushion tire including spaced inner and outer circular flexible bands, innery and outer continuoussinuous flexible bands disposed between said circular bands and arranged in respective-parallel relation, the

inner and outer portions of said inner and cuter sinuous bands respectively being secured in staggered relation to said inner and outer circular bands respectively, an intermediate continuous sinuous l flexible band disposed between Asaidsinuous bands and arranged with its curves arranged opposite to the curves of the latter, the inner and outer portions of said intermediate band being secured to the outer and inner portions respectively of said inner and outer sinuous bands respectively, and diamond shaped. cushion blocks secured at opposite corners between said inner and intermediate sinuous bands to the respective inner and outer por.-

tions of the curves'of the saine, andbetween said intermediate and outer sinuous bands to the respective inner and outer portions ofthe curves thereof.

4. A structure as specified in claim l, the

bands vbeing of fabric and coated with rubber." l. l
